FORM HANGER Filed May 8, 1933 ATTORNEYS Patented Sept. 11, 1934 UNllD srAres PATENT oFF cE FORM HANGER Ted D. Anderson, Detroit, Mich. Application Mays, 1933, Serial No. 669,825 V 7 Claims. (01. 25131.5)

The present invention relates to a novel form hanger of a type particularly useful in building forms for concrete structures.

The primary object of the present invention is to provide a novel hanger of a type particularly adapted for supporting form members in proper relation to structural beams so that the latter may be encased in concrete by pouring the same in the form supported by said hanger.

Another object of the present invention is to provide a combined hanger and spacer for supporting form members relative to structural beams in definitely spaced relation relative thereto.

Still another object of the present invention is to provide a combined form hanger and spacer for supporting form members in definite spaced relation relative to a structural beam so that said beam may be encased in concrete, the 20 hanger being provided with supporting members for securing a form reinforcing cleat in place which serve for the purpose of securing wire lath in place after the concrete has been poured, allowed to set, and the form members removed.

With the above and other ends in view the invention consists in matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which Figure 1 is a cross section of a form supported adjacent a structural beam by the present hanger;

Fig. 2 is a cross section, with parts in elevation, taken along the line 2-2 of Fig. 1;

Fig. 3 is a cross section taken along the line 33 of Fig. 1;

Fig. i is a perspective view of the hanger;

Fig. 5 is a perspective view of a wedge member to be associated with the hanger, and

Fig. 6 is a view of the blank from which the present hanger is formed.

Like characters of reference are employed throughout to designate corresponding parts.

In the drawing the numeral 1 indicates a 45. structural beam, shown by Way of example, it

being understood that the invention to be described is not limited to any specific type of beam. In building construction it is the practice to encase the metal beams in fire-proof material, such as concrete. Inasmuch as the concrete is to be poured around the beam the same is enclosed in a form suitable for receiving the concrete to hold it in the proper relation to the beam until it becomes set or hardened. The form for receiving the concrete comprises a deck 2, beam sides 3 extending downwardly from the deck adjacent the edges of an opening, therein through which the structural beam extends, and a beam bottom 4. This invention relates. specifically to the means for securing the beam bottom 4in place and through the beam bottom to maintain the beam sides in place.

It will be understood that the beam bottom is formed on a bench, separate from the instal lation into the form, it being provided with transversely extending cleats 5 thatextendqoutwardly from the sides thereof to provide sup port for the beam sides, the lower edges .of which directly engage the cleats.- Blocks. or strips .6 are secured to the cleats to prevent spreading movement of the beam sides. 7 It is obvious, therefore, that by securing the beam bottom in definite spaced relation tothe structural beam 1 the beam sides are also secured in definite relation. I

The means for securing the beam bottomto the structural beam comprises a sheet metal bracket including a vertical wall 7, and a horizontal base wall 8, and laterally extending reinforcing flanges 9. Extending downwardly from the laterally extending flanges 9 are a pair of arms 10, the arms being maintained in spaced relation as a result of the manner in which the flanges 9 are formed on opposite sides of the vertical wall 7. An opening 11 is stamped in the wall 7 and the metal therefrom extended outwardly at right angles to the vertical wall in the form of a lip 12. A pair of spaced slots 13 are formed in the wall 7 and a pair of fingers 14 formed also therein by stamping the metal adjacent theslots outwardly. A wedge member 15 is provided with a pair of wedge shaped arms 16 and with openings 17.

In assembling a concrete form by use of the present hanger the base plates 8 are secured by bolts 18 to the form bottom 4 adjacent the edges thereof so that the arms 10 extend downwardly from the edge thereof. The arms 10 are then secured by bolts or nails 19 to the cleats 5. It will be noted that the vertical walls 7 ex-' tend upwardly in relation to the top of the form bottom 4. The form bottom is then moved to a position where the walls 7 of opposite hangers extend upwardly adjacent the structural beam 1, at which time the arms 16 on the wedge members are inserted through the slots 13. The lip 12 on each hanger engages the bottom of the flange on the structural beam 1 and the wedge arms engage the top of the flange and therefore by driving the wedge arms 21' v inwardly the flange is tightly interposed between the lip 12 and wedge arms. The fingers 14 extend through the openings 17 in the wedge members 15 and are then bent over as at 20 to retain the wedge member in its wedging position.

Although a specific embodiment of the present invention has been illustrated and described it is to be understood that various changes may be made in the details of construction without departing from the spirit of the'invention, as set forth in the appended claims, and such changes are contemplated.

What I claim is:

1'. A device of the character described .comprising a hanger member a removable wedge member adapted to cooperate with means on said hanger for securing the sameto a supporting member, and means integral with said jhanger member and adapted to be bent over said wedge for securing said wedge member in a wedging position.

2. -A hangerqformed with a plurality of slots and having a protruding lip, a wedge member supported in said slots and adapted to cooperate withsaid lip in tightly engaging a supporting member, and means integral with. saidhanger for preventingmovement of said wedge member from a wedging position.

received in said supporting means and adapted to engage the upper surface of said supporting T member to tightly inter-pose the latter between said first named meansand said wedge, and a finger on said bracket adapted tobe bent over said wedge to retain it in a wedging position.

4. A device of the character described comprising a bracket, a projecting lip on said bracket adapted to engage the bottom surface of a supporting member, said bracket being formed with a slot, a wedge member slidably received in said slot and adapted to be moved to a position of engagement with the upper surface of said supporting member, and a finger on said bracket adapted to be bent over said wedge to retain it in a position of engagement with said supporting member.

5. A device of the character described comprising a sheet metal bracket, said bracket having a struck out portion providing a lip adapted to engage the bottom of a supporting member, said bracket being formed with a pair of spaced slots, a substantially U-shaped member vhaving wedge shaped arms extending through said slots and adapted to be moved into wedging engagement with said supporting members, and a finger formed integral with said bracket and adapted to be bent over said wedge member to retain it in wedging engagement with said supporting members.

6. A device of the character described for use in combination with a supporting member and a form panel, said device comprising a bracket having means for engaging said supporting memher, a wedge member for causing wedging engagement of said means with said supporting member, vmeans integral with said bracket and adapted to be bent over the wedge for retaining 100 said wedge in a wedging position, and depending arms on said bracket adapted to extend, through said panel for the purpose of supporting a cleat.

- '7. A device of the character describedfor use 105 in combination with a supporting member and a term panel, said device comprising a bracket, means .on said bracket adapted tov engage the bottom of said supporting member, said bracket being provided with means for supportingv a 1.10

wedge, a wedge received in said supportingmeans and adapted to be moved into wedging engagement with said supporting member, a finger on said bracket adapted to be bent over said wedge to retain it in a wedging position, and an arm depending from said bracket and adapted to extend through said form panel for the purpose of supporting a cleat..
